Ordinance
on Protection against Dangerous Substances and Preparations
(Chemicals Ordinance, ChemO)

¹ Man­u­fac­tur­ers of pre­par­a­tions may use an al­tern­at­ive chem­ic­al name for a sub­stance if:

a.

they demon­strate that dis­clos­ing the name of the sub­stance on the la­bel or in the safety data sheet would put the con­fid­en­tial nature of their busi­ness, in par­tic­u­lar their in­tel­lec­tu­al prop­erty rights, at risk; and

b.

the sub­stance meets the cri­ter­ia spe­cified in Sec­tion 1.4 of An­nex I to the CLP Reg­u­la­tion, in the ap­plic­able ver­sion re­ferred to in An­nex 2 num­ber 1.

² The al­tern­at­ive chem­ic­al name shall be a name that iden­ti­fies the most im­port­ant func­tion­al groups or serves as an al­tern­at­ive des­ig­na­tion.

³ If the European Chem­ic­als Agency has ap­proved the use of an al­tern­at­ive chem­ic­al name in ac­cord­ance with Art­icle 24 of the CLP Reg­u­la­tion, the use of the name is deemed ap­proved in Switzer­land from the date on which the No­ti­fic­a­tion Au­thor­ity ac­know­ledges the fol­low­ing doc­u­ments and data:

a.

the de­cision of the European Chem­ic­als Agency;

b.

de­tails of the sub­stance iden­tity in ac­cord­ance with Art­icle 49 let­ter c num­bers 1–3.⁵³

^3bis Where the name and iden­ti­fic­a­tion num­ber in the clas­si­fic­a­tion and la­belling in­vent­ory in ac­cord­ance with Art­icle 42 of the CLP Reg­u­la­tion is used when the chem­ic­al name in ac­cord­ance with Art­icle 18 para­graph 2 let­ter b of the CLP Reg­u­la­tion is used, if the No­ti­fic­a­tion Au­thor­ity so re­quests, the sub­stance iden­tity in ac­cord­ance with An­nex VI Sec­tions 2.1–2.3 of the REACH Reg­u­la­tion⁵⁴must be provided.⁵⁵

⁴ The use of an al­tern­at­ive chem­ic­al name may be re­ques­ted for a pre­par­a­tion:

a.

in a spe­cif­ic com­pos­i­tion;

b.

with a spe­cif­ic trade name or a spe­cif­ic des­ig­na­tion; and

c.

re­served for cer­tain uses.

⁵ Au­thor­isa­tion to use an al­tern­at­ive chem­ic­al name is gran­ted to the man­u­fac­turer and is non-trans­fer­able.

⁶ The use of an al­tern­at­ive chem­ic­al name by the man­u­fac­turer and pro­fes­sion­al users in the same sup­ply chain is per­mit­ted without au­thor­isa­tion for the first six years after:

a.

the re­port­ing, de­clar­a­tion or no­ti­fic­a­tion of a new sub­stance;

b.

the re­gis­tra­tion of a sub­stance that falls un­der Art­icle 119 para­graph 2 let­ter f of the REACH Reg­u­la­tion and in re­spect of which proof of re­gis­tra­tion and de­tails of the sub­stance iden­tity in ac­cord­ance with Art­icle 49 let­ter c num­bers 1–3 are sub­mit­ted to the No­ti­fic­a­tion Au­thor­ity.⁵⁶

⁷ If no re­quest to use an al­tern­at­ive chem­ic­al name and no de­cision from the European Chem­ic­als Agency nor the in­form­a­tion in ac­cord­ance with para­graph 3 are sub­mit­ted with­in the peri­od spe­cified in para­graph 6, on ex­piry of the peri­od the chem­ic­al name in ac­cord­ance with Art­icle 18 para­graph 2 of the CLP Reg­u­la­tion must be used.⁵⁷
